4 claims. (ci. 15s-106) My invention-relates to 'an improvement in gas burners. One of the objects of my gas burner is to provide a burner that will operate efficiently on a low gas pressure as Well as on a high gas pressure. Another object is to 'provide a gas burner which willhaveflittle or no flash back after the gas has been `turned off. A still further .object is to provide a gas burner which will have no flash back during the time it is burning, even though-the gas pressure is extremely low. YThese n and other 'objects will be more Afully explained as this description progresses.l

Now referring to the drawing in which the throughout the'several 'iiguresv Fig. 1 is a plan View of my improved gas burner unit. Fig. 2 is a sectional View throughfmy gasburner kunit as viewed from the line II`II in Figjf3. Fig. 3 is a 2O longitudinal sectionalv view through my gas burner unit. 4 Fig. 4 is a plan view of -my gas burner unit with the gas grate removed and'with parts being broken away for convenience of illustration. Fig. 5 is a perspective jviewf of the bottom side of the gas grate. Fig. 6` is a perspective View of a gas burner` assembled from `my improved gas burner units. 1 i 1 VIn the drawing is shown my- Aimproved gas burner unit comprising abox-like element' 10 which is open at the` topand having an integral bottom 11 andVenturi tube 12 which is open at either end and -is integral with the bottom 11 and passes therethrough. Positioned lwithin the box and over theVenturi tube 12 is-a second box-like element 13 having an open bottom and an integral closed top 14. At the bottom of the walls .of the box-like element 13 arejcut away portions or openings l5 between which are formed leg or support elements 16 which rest on the bottom 11 and support the box-like element13. Integral with the box-like element 13 and top-14 and at the corners thereof are outwardly extending portions 17 which are so positioned that they t in the corners formed by the walls of the boxlike element 10 and serve to properly space the walls of the box-like element 13 from the walls of the box-like element 10.

At 18 is shown a gas gratev positioned within and preferably even with the top of the walls of ythe box-like element 10. On the bottom side and at the 'corners ofthe gas grate are shown legs 19 which rest on the corner projections 17 and support the gas grate a spaced distance above the top 14 of the box-like element 13. `The gas grate is composed of a plate or casting 18 having a plurality of narrow slots or openings 2'0-extendlsame reference characters refer to the same parts v ing lfrom the edges of the plater 18 inwardly towardv the center axis 'of the plate 18.l VEach of said slots runs transversely to the center longitudinal axis and each slot 20 isa little shorter than the adjacent one next toward the trans'- verse center axis. The object of this arrangement ofthe slots 20 is that a large volume of secondary air may enter at the ends of the plate 18 and pass over the plate toward `the transverse axis ofthe plate, then between each of the slots 20 to aid in the combustion ofthe gas .arid air 'mixture being-emitted from the slotsY 20 as will be later explained,

At 21 is shown a frame having a plurality of vseats or sockets in which a plurality of my gas burner unitsV A may be loosely and removably set .and held.V The lframef2l carries a gas manifold or a plurality of gas manifolds 22 if necessary, which are positioned so they cross the center perpendicular axis of the gas burner units A. In the `gas manifolds 22 are gas openings or `iets 23 so positioned that gas being discharged through the gas opening or jet 23 will pass directly into and up the Venturi tube. 12. Y

The operation Vofmy improved gas burner unit is as follows: Gas is fed to the gas manifold 22 from` any suitable source of supply and dischargedfrom the manifold22 through the gas Yopening or jet 23 into the Venturi tube 12 Whereupon air from the outside orV around themanifold 22 is drawn intoy the Venturi tube 12 by the fiiow of gas being jetted into the tube and the .gas and air togetherliow upwardly in the VenturiI tube V.and are discharged therefroinV and 'against the top 14 of the box-like element 13 whereupon the line of travel of the gas and air is diverted and caused to ow downward inthe box-like element 13, whereupon a mixing of the 1 gas and air takes place and at the bottom of the box-like element 13 the line of travel of the gas and air mixture is again diverted so that the gas and air mixture passes through the openings 15 into kthe box-like element 10 whereupon the gas and air are thoroughly mixed and the mixture passes upwardly in the box-like element l0 and is finally discharged through the slots 20 where- Y upon 'secondaryair comes up around the outside of the box-like element 10 and over the grate :plate 18 and passes between the slots 20 and mixesrwith the gas and air mixture being discharged through the slots 20 whereupon complete combustion of the gas and air mixture takes place.

In Fig. 6 Ivhave shown a gas burner composed of six gas burner units A, however a gas burner may comprise only one of my gas burner units or it may comprise as many gas burner units as are necessary to obtain the desired heating result.

In the drawing I have shown my improved gask burner unit as having a` rectangular box-like form, however it will be understood that numerous box-like forms such as elliptical, round, square, triangular or any other polygonal shape or form may be `made and still obtain satisfactory results from the burner unit.

Such modifications may be employed as lie within the scope of the appended claims without departing from the spirit and intention of my invention. Now having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a gas burner unit, said gas burner-unit comprising a first and a second box-like element,

said second box-like element beingpositioned within the first said box-like element, saidrfirst box-like element having an open top and anl integral closed bottom inwhich is an integral Venturi tube passing through said bottom, said Venturi tubevbeing positioned vertically on the vertical center axis of the first said box-like element, said second box-like element having an open bottom and an integral closed top, openings in the bottom portion of the walls of said second boxlike element and integral outwardly extending portions at the upper corners of said second box-like element, said outwardly extending portions tting in the corners formed by the walls of the first said box-like element, a gas grate, said gas grate being positioned within and at the top of the walls of the firstv said box-like element and means for supporting said g gas grate in said position, and means for entering gas and air in said Venturi tube.

` 2. In' a gas burner unit, said 4gas burner unit comprising a first and a second box-like element, said first box-like element having an open top and an integral closed bottom, said bottom having an integral Venturi tube passing therethrough, said Venturi tube be'mg positioned on the vertical center axis of the rst'said box-like element, said second box-like element being oontained in said first box-like element, :said second box-like element having an open bottom with openings in the lower portion of the walls of said second box-like element, and an integral closed top, said second box-like element being positioned over said Venturi tube, and means on said second box-like element to properly space its walls `away from the walls of the rst said box-likeelement,
